LK Brothers Engineering provides professional aircon servicing, chemical wash, overhaul, gas top-up, and installation across Singapore.

For homes in Singapore’s hot and humid climate, your aircon should be serviced every 3 to 4 months to maintain strong cooling and prevent water leaks. Regular aircon servicing improves energy efficiency, reduces breakdowns, and extends your aircon lifespan.
A professional aircon servicing includes cleaning air filters, checking refrigerant gas, washing evaporator coils, clearing drainage pipes, and testing overall system performance. Our technicians ensure your aircon cooling efficiency is restored to optimal condition.
Aircon chemical wash is a deeper cleaning process compared to general servicing. It removes stubborn mould, dirt, and bacteria from the coil and blower unit using a safe chemical solution — ideal when your aircon is not cold or leaking water.
An aircon chemical overhaul is recommended if your system still performs poorly after a chemical wash. It involves full dismantling and deep cleaning of all components, restoring your aircon’s cooling power and prolonging its lifespan.
If your aircon is blowing warm air or taking longer to cool the room, it may require a gas top-up. Our technicians check for refrigerant leaks and refill the correct gas type (R32 or R410A) for efficient cooling.
Yes, we provide aircon installation for all major brands in Singapore, including Daikin, Mitsubishi Electric, Panasonic, Midea, and LG. Our installation includes site inspection, proper pipe routing, and full testing for safety and performance.
If your aircon is still not cold after servicing, the issue may be due to low refrigerant gas, dirty coils, or a faulty compressor. We recommend a full system check or aircon chemical wash to restore proper cooling.
The aircon servicing price in Singapore starts from around $16.50 per unit, for contract servicing. Price may vary depending on service type and aircon condition. LK Brothers offers transparent, affordable pricing for aircon cleaning, repair, chemical wash, and installation.
Yes, we offer emergency aircon repair services across Singapore. Our experienced technicians can handle sudden breakdowns, leaks, and system errors quickly — available for both residential and commercial units.
